Description

A Spunding Valve is used to adjust and release pressure on a pressure capable fermenter, such as a Unitank.  It can  also be used to release pressure from a keg while filling or filtering. The relief valve can be adjusted to release pressure from 0-15 psi.

Caution: This Spunding Valve should never be used as the primary safety pressure relief device.  Every vessel that is under pressure should have a primary safety relief valve set in accordance with the pressure rating of the vessel. This Spunding valve should only act as a seondary relief that also allows you to adjust the pressure within the safety limits of the vessel or tank. 

How to Adjust: The pressure relief valve is adjusted by unscrewing the very end which reduces pressure on the spring. If tight, and not adjustable by hand, it needs to be loosened with pliers. Wrap a towel around the end piece of the pressure relief valve (about  the last 1/4 in) and loosen with pliers. Then finger tighten or loosen to your desired pressure.

 
Gauge reads 0 - 15 psi

Does what it's supposed to do
I read the above reviews and acted on faith in MoreBeer and bought it any way. Turns out it works very well and does what it is supposed to do. It can be a bit tricky to get the setting right, but once you do, it's fine.

Both leak
I bought two of these and put them on a keg to check them for leaks. Good thing I did because both leak. I only started messing with one and the whole assembly was loose, so I tightened it all up. However, the pressure release valve at the end is now leaking. Have yet to look into the second one yet.

Want this with 0-30 PSI gauge
I like that this version of the pressure relief valve has a gauge on it, and it would work well for keg to keg transfers, but for those of us that would like to do natural keg carbonation in ambient temperatures without over carbonating, we need the gauge above 15 PSI. For example, to achieve 2.5 volumes of CO2 in 67F temperature, the PSI would need to be 27.1.
